KBM shows you how much time each battery percent lasted.
It estimates how long it will take to charge X battery percentage.
It also show some charge cycle information.
What do you think about it, Is there anything that I can improve/add?
Could actually be very useful for battery tests, finding the best kernel for you, etc. Really nice man.
I don't really think there's much you should change. Maybe a 'Save Log' option and a GUI change? Other than that, very nice !
Very good. Maybe you can add an option to show how much time the battery lasted in total, and an option to save the result. I have some batteries, it would be great to compare their perfomance.
